The body is strongly compressed, elongate and 

 very low, arici of almost uniforrn- height, the hinder 

 part though is a trifle^ higher than the fore. Its great- 

 est height is contained- about fifteen times in its 

 length. 



The head is very small; its length goes once and 

 a half into the body's greatest height. Its upper pro- 

 file is in the form of a regular arch. The snout is 

 pointed. The interspace between the snout-extremity 

 and the anterior margin of the eye is about half as 

 great again as the eye's diameter. The eye has a 

 circular contour; its upper margin does not reach to 

 the head's upper profile. The posterior nostril is situ- 

 ated a little in front of the eye; the anterior about 

 as far from the posterior as from the snout-extremity. 

 The cleft of the mouth is horizontal extending to some- 

 what behind the middle of the eye's under margin. 

 The lower jaw is a little shorter than the upper and 

 has an under profile that is slightly convex retreating 

 with a somewhat prominent angle. Teeth in both jaws. 



The pectoral fins are extremely rudimentary. The 

 vertical fins are also - very slightly developed ; the dor- 

 sal fin has its origin immediately in front of the vent ; 

 the caudal fin is very short and bluntly pointed. 



The vent is situated in front of the body's middle. 



Along the lower side of the body from the throat 

 to the vent extends a row, at many points discontinuous, 

 of very minute, closely packed pigmentary spots; an- 

 other row of somewhat larger spots, further apart,
